The NO₂ levels measured by Sentinel-5P in mid-October are higher than those measured at the beginning of March 2021 (values 0.125 mmol/m2 higher than the 0.1 mmol/m2 in March). This results from the presence of a strong high pressure system that affected atmospheric circulation and caused a widespread deterioration in air quality.
The Copernicus Sentinel-5P mission is the first Copernicus satellite mission dedicated to monitoring the composition of the Earth's atmosphere. Its main objective is to perform measurements of air quality, climate forcing (external factors, such as greenhouse gas emissions or volcanoes, which affect the climate’s energy balance), UV radiation and ozone concentration with high spatio-temporal resolution.
